ANTICREEPING- DEVICE FOR RAILWAY RAILS.

Application filed July 3,

The invention relates to anticreeping devices of that class in which a rolling member is interposed between the edge of the baseflange of the rail and an adjacent fixed surface on the tie-plate, adapted to engage such edge and surface by a cramping action induced by the creepin movement of the rail relatively to the tie-plate, and it relates more particularly to that type in which the enlo gaging member is in the form of an elliptical roller.

The object of the invention is to provide simple and eflicient means for introducing the roller and insuring its engagement with the rail and tie-plate in proper operative relation to both.

The invention consists in certain novel features of construction and arrangement by which the above objects are attained, to be :0 hereinafter described and claimed.

The accompanying drawings form a part of this specification and show the invention as it has been carried out in practice.

Figure 1 is a plan view showing a portion 26 of a rail supported upon and engaged with the improved tie-plate.

Figure 2 is a vertical section of the same arts taken transversely of the rail, on the ine 2-2 in Figure 1, showing the roller partially inserted.

Figure 3 is a plan or top view of the rollin member alone, on a larger scale.

%igure 4 is a side elevation corresponding to Figure 3.

The rail is of standard type having the head 5, vertical web 6 and base-flanges 7 and 8, supported on a tie-plate 9 and held in place thereon and to the tie, not shown, by spikes 10 in any approved manner.

On the upper face of the tie-plate, near one end, is a transverse abutment 11 extending parallel with the outer base-flange 7 serving to hold the latter against outward lateral movement. On the upper face of the tie-plate and oppositely disposed to the abutment 11, is a ridge 12 extending the full width of the plate, and having a face 13 which is presented toward the inner basefiange 8. This face is plane, perpendicular to the face of the tie-plate and parallel with the edge of the base-flange 8.

The face 13 is formed by undercutting the ridge to produce an overhanging 11p 14 projecting toward the rail, and at about the mid-length of the 11p is a semi-elliptlcal 1926. Serial No. 120,270.

notch 15 extending from the edge of the lip to the face 13.

The rolling member 16 lies in the space between the face 13 and the base-flange 8, and is elliptical in plan with the main portion of its periphery perpendicular to its base and is provided with vertical corrugations or teeth 17 The upper and lower peripheral margins are chamfered or beveled circumferentially as at 18 to avoid the formation of burrs or roughnesses on the plane faces in the operation of forming the teeth 17.

The minor diameter of the toothed roller 16 is slightly greater than the space between the base-flange 8 and face 13 and the roller is inserted in such space by lacing it in the notch 15 at an angle to t e tie-plate, as shown in Figure 2, with its periphery in contact with the base-flange 8, it is then driven by blows of a hammer until its underface contacts with the upper face of the tieplate. This forcible insertion causes the teeth 17 to bite into the edge of the baseflange 8 and the face 13 and thus insures positive engagement with those surfaces.

Thus engaged a movement of the rail relatively to the tie-plate causes the frictional bite or pinching action to increase as the major diameter of the ellipse widens relatively to those surfaces, with the result that the movement of the rail is effectually resisted and stopped when the roller has travelled a short distance.

As the roller matches closely to the notch 15 such travel engages a portion of the roller beneath the overhanging lip 14, see Figure 1, and prevents the vertical escape of the roller.

The device is intended to avoid the possibility of errors by employees in equipping the rails against creeping 1n the direction of travel.

In the use of old methods the rollers had to be placed and engaged with reference to such travel in order to hold the rail; by the use of the present invention such care is no longer required, it is only necessary to introduce the roller in the notch and drive it home as above described, irrespective of the direction of travel.

I claim In an anticreeping device, a tie-plate adapted to support a rail, an abutment on said plate adapted to lie against the outer base-flange of said rail, a ridge on said plate adjacent to and separated from the innerbase flange of said rail, said ridge having-a vertical surface presented toward said inner base-flange and para-llel therewith, said ridge having an overhanging lip, and a vertically corrugated elliptical rolling member located in the space between said surface and edge of said inner base-flange, adapted to engage frictionally with said surface-and edge, said lip having a notch arranged to permit the 10 insertion of said rolling member into said space.

In testimony that I claim the invention above set forth, I affix my signature hereto.
